What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination with the closet-bowl, seat-frame and seat hinged thereto, of the suction-fan D, and a water-wheel F mounted upon the shaft G,the casing E mounted upon the seat-frame and inclosing said fan and wheel, the discharge-spout L formed at the base of the casing and extending at an incline through a recess in the top of the seat-frame into the bowl over the rear edge thereof, the recess N in the under side of the seat, the trunks I and J connecting said discharge spout with the fan and the water-wheel, the supply-pipe O for the water-wheel, the valve P in said *snpply-pipe and the actuating valve-stem 0 arranged to automatically operate the valve by the movement of the seat.

2. In a ventilating device for Water-closets, the combination with the bowl and seat-frame, of a suction-fan having an actuatingQ aterwheel secured upon a common shaft, and a casing mounted upon the seat-frame, and formed with separate compartments inclosing said fan and wheel, said casing having a lower section or base recessed into the seatframe and communicating through openings and passages in the casing with the said compartments, and through a discharge-spout formed on said lower section and extending into the top of the bowl with the interior of the bowl, to form a common conduit for the discharge of the waste Water from the waterwheel into the bowl and for the admission of foul air from the bowl into the suction-fan.

3. In a ventilating device for water-closets, the combination with the bowl, seat-frame and seat hinged thereto, of a suction-fan and actuating water-wheel arranged upon a common shaft, a casing formed with compartments inclosing said fan and water-wheel, a pan recessed into the seat-frame and forming a lower section or base upon which the casing is mounted and with which its compartments are in suitable communication to receive the waste water from the water-wheel and for admitting air to the fan, said fan formed with an inclined bottom, and a discharge-outlet extending through the seat-frame and projecting over the rim of the closet beneath the rear portion of the seat, said seat formed on its under side with a recess through which said discharge-spout is brought into open communication with the interior of the bowl.

4. In a ventilating device for water-closets, the combination with the bowl, seat-frame and seat hinged thereto, of a suction-fan and actuating water-wheel upon a common shaft, a casing inclosing said fan and wheel and provided with inlet and outlet openings in its bottom for the discharge of the waste water from the wheel and for the admission of air to the fan, a pan recessed into the seat-frame to one side of the center of the closet and forming the base upon which the casing is mounted, a discharge-spout on said pan extending beneath the rear end of the seat and communicating with the interior of the bowl, and a valve for automatically controlling the admission of water to the water-wheel, said valve having its casing secured to the under side of the pan and having its stem projecting through the bottom of said pan into contact with the under side of the hinged seat.

5. In a ventilating device for Water-closets, a suction-fan and actuating water-wheel arranged upon a common shaft, a casing formed with compartments inclosing said fan and water-Wheel, a pan forming a lower section or base upon which the casing is mounted and with which its compartments are in suitable communication to receive the Waste water from the Water-wheel and for admitting air to the fan, said lower section or base being connected with a discharge-outlet which may be extended underneath the seat-frame and project over the rim of the closet or connected with the local vent thereof, and a valve for automatically controlling the admission of Water to the Water-wheel, said valve having its casing secured to the under side of the discharge-outlet and having its stem. projecting in such manner as will admit of its being actuated by the movement of the hinged seat.

In testimony whereof I affix my signature in presence of two witnesses.

ALBERT DROUILLARD.
